Title: Rubber coupling flange for reinforced rubber hose - has hose reinforcement clamped in flange by compressed rings
Inventor: WILCKE RUDOLF
IPC: F16L33/28
Filed: 1976-03-03
Abstract: A fixing flange of rubber is integrally formed with a rubber hose and comprises perforations and also contains the hose reinforcement, embedded in the flange and in the rubber hose. The flange also contains a clamping device, which firmly clamps the hose reinforcement (in)directly under tensile loading. For indirect clamping, there is pref. a rear back-up flange of metal or other suitable material, behind the rubber flange, and also an annular disc embedded in the rubber flange. The clamping device here comprises concentric rings, near to the back-up flange and penetrating into the rubber fixing flange, so that the hose reinforcement is clamped between these rings and the annular disc, in regions where the rubber is constricted by the pressure of the rings. For direct clamping, a pref. min of three rings in one group is associated with three corresp. but staggered rings in another gp., the hose reinforcement being conducted between these two or three layers of rings and clamped there in an undulating pattern. One set of rings may be fixed to the back-up flange and the other set to the annular disc. The rings are pref. of metal or other suitable material. Used esp. for coupled hoses subject to high tensile loading or sharp bending. The arrangement ensures that these loading conditions can be tolerated without the reinforcement becoming detached or loosened from the flange.

Title: Semiconductor elements with three zones - are produced from substrate with impurities diffusion from both main surfaces
Inventor: MUELLER JOERG DR ING
IPC: H01L21/265
Filed: 1976-03-17
Abstract: The produced semiconductor element has a middle zone and two adjacent zones. First a semiconductor substrate with two opposite main surfaces is produced. Its thickness does not exceed the total required for the three zones. Then impurity locations are formed from both main surfaces by diffusion. The diffusion produces the two semiconductor zones adjacent the middle one. Alternately the impurity location may be produced by ion implantation. The impurities may be deposited simultaneously. The diffusion material is preferably deposited on the surfaces in form of a layer prior to the simultaneous diffusion. An aperture in the substrate insulating film may be used for this purpose.

Patent DE-2616556-A1 (DE)
Title: Dehumidification of air in enclosed spaces - esp. for textile processing e.g. in fabric printing
Inventor: GALI MALLOFRE SALVADOR
IPC: F24F3/14
Filed: 1976-04-14
Abstract: The moisture is condensed from the air in the enclosure in a system which incorporates a heat exchanger. The air flows through one side of the heat exchanger where it is precooled and some condensation can take place. On leaving the heat exchanger, the air is sub-cooled by passing through a refrigeration system which condense further moisture. The fully cooled air passes in countercurrent through the other side of the heat exchanger and is warmed by exchange with the incoming air. The recuperator is in the form of a plate heat exchanger, in which a pak of parallel plates enclose the passages for the two streams which flow in alternate passages. The wide passages are divided up by longitudinal baffles into smaller parallel passages. Preheated air leaving the recuperator is raised to the finally required temp. by passing through a heat exchanger in which the recompressed refrigerant is condensed. The temp. is controlled by partial condensation of the refrigerant in a water cooled condenser. The air is exhausted conventionally, e.g. by a fan. The dehumidifier can be mass produced, and the required duty is achieved by using multiple units. The equipment is made in the form of a readily moveable packaged system. The energy consumption is minimised using a recuperator. The required air temp. and humidity can be achieved regardless of outside atmospheric conditions. The system is safe in operation having a low fire and accident risk, and achieves a high efficiency in relation to its cost.

Title: Weft insertion in looms by platen comb - effected more efficiently by alternately arranged plain and nozzle platens
Inventor: SCHEFFEL WALTER
IPC: D03D47/30
Filed: 1976-05-19
Abstract: The channel formed by the platens through which the weft is projected, diminishes in height in the direction at right angles to the plane of the reed, to end in a rounded front wall. In the direction of insertion also, the passage narrows between two platens having flow outlets, whilst each of the other platens has a wider opening towards the reed than the preceeding bored platen. The weft passage opens in steps and each outlet for the propellant fluid, directed into this wider channel, is inclined to the axis of the passage. The jets move farther away from the reed and do not intersect the plane in which the jet outlets are positioned. The thickness of the platens increases forwards from the reed and is greatest at the narrowest point of the weft passage. The warp threads which lie on the feed pipes to the nozzles are protected by the noses of the platens which project above the flow outlets. Nozzles suitably designed for a good flow and a new shape.
